Petrology and geochemistry dataset of lava from the Ijen Crater and Mount Blau Banyuwangi East Java Indonesia

摘要

This article presents rock texture and mineralogy, as well as major and trace elements of lava from Ijen Crater and Mount Blau, Ijen Volcanic Complex (IVC), East Java, Indonesia related to article entitled “Rock Magnetic, Petrography, and Geochemistry Studies of Lava at the Ijen Volcanic Complex (IVC), Banyuwangi, East Java, Indonesia” [1]. Six lava samples were taken from three lava flows that are the product of the eruption of the Ijen Crater and three lava samples from a lava flow that is the product of the eruption of Mount Blau. The samples were crushed and used for measuring major and trace elements using XRF method. Meanwhile, the thin sections of all samples were used to analyze rock texture and mineralogy. These data are invaluable in identifying the lithology, tectonic setting, and magmatism process through the analysis of total silica alkaline and Harker diagram. Other researchers can analyze the other diagrams and graphs to know in more detailed information as intended. On the other hand, the data can be used as a comparison for other lava products from different eruption sources.
